Crushed stone varies in size. The number "57" is a number that refers to the size sieve that was used to screen and sort the stone. It means that the stone was put through the #57 sieve which produces gravel stones of about 1" to 1.5" in size. #1 crushed stone refers to the largest sized crushed stone. It is about 2″ to 4″ in size.

Crushed stone's varying sizes and angular shapes make it an excellent base material for driveways and roads. It locks together under compaction, providing a stable surface. Conversely, #57 stone, with its uniform size and shape, is also used in these applications, particularly when consistent drainage and aesthetics are primary concerns.

Unlike clean gravels, crusher run gravel will also contain a mix of fines like screenings (stone dust) or dirt that blends together with the angular crushed stone - giving crusher run its desirable compaction and drainage properties. The product can typically range in sizes from 1/2" to 4" stones with fines.

A gravel or stone driveway requires maintenance. Every few years they need refreshing.
